Letters Patent No. 95,510, dated October 5, 1869.

HOT-AIR REGISTER.

The Schedule ijeferred to i'n these Letters Patent and making part of the same I Y To all whom' it may `concern Be it known that I, HUGH M. PHINNEY, ot' Cambridge, in the county of Middlesex, and State or' Mas nianner of pivoting valves, or to the construction. ot'

the valve-frame with reference to pivoting the valves.

The invention consists primarily inhanging, upon the front or outer side ot' the register-plate, astar or pointed lever, one arm or point of which projects int-o the slot ot' the slide by which the valves' are worked, while two other arms or points project in opposite right-angular directions from the first arm, and serve for the attachment ot' vertieallyfhanging cords or lines, by means of which the. lever is worked to actnate thc slide, and open and close the valves. l

The invention further consists in casting in one side of the frame, in which the valves' are pivot-ed,(the four walls of which frame are cast integral,) pivot-bearings, into which thc pivots at one end of the. several valves are inserted endwise, a suitable plate holdingl down the opposite pivots.

The drawings represent a hot-ah,- register embodying my improvements.

A shows a plan ofthe register'.

B, a section on the liuc a; x.

"C, a section on vthe liuc y y.

a denotes the register-plate.

b, the box-frame by which the register-is set'into a wall or floor-,and in which is hung the series ot' blades or valves c, by opening and closingw'hich the passage ofhot air through the register' is regulated..

Each valvec has, at its opposite ends, pivots d (I, by which the valvel is sustained; thesepivots being himg in bearings ef formed on the frame b.

At one end of the frame each bearing extends into the vertical wall, as seen at B, and thereby supportsthe pivot on all sides, while at the other end a hearing-k plate, g, is screwed to the wall, as seen at B, the slots in this plate, and the corresponding slots or depress sions in the ange h of the tranne, iorming the bearings for the adjacent pivots.

By forming the bearings for the valve-pivots at one end' of the valves, directly in the end wall, and so that the bearings surround the pivots, and making the bearingsat the other end, one-halfin the tiange hand onehalf in` the plate g, Ipdispeuse with an independent bearing-plate at one end of the register, first slipping the pivots endwise into position into the bearings e, and

ingsj, and. fastening over them the plate g.

At the end of the register where the bearings eare' located, is the slide i', by which the valves are opened or closed.

This slide rests and moves upon projections lr, and does not touch the valve-pivots. It has a Series of slot-s l, into each of which projects, respectively, a'pin, fm., extending from an ear, a, cast upon-'each valve.

(in the upper end ot' the slide isa projection, .1, which, extending through 'the register-plate a, serves to operate the slide, to open or close the register.

When the register is set into a tloor, the slide may be moved b v the foot or by the hand applied to the projection r,- but to enable' thc register t'rbe'as easily operated when placed at lthe top ol' a wall, I apply thc star-wheel or lever o.

'lnis lever is nia'de with three or more anus p, the end or point ot' one of which projects into a slot in the slide-projection ras' seen :tt-A, while tothe-rend of the two arms, projecting right-angularly from this arm,

are attached the vertically-lranging cords, by means ol' which the lever is actuated, the. lever being tnlcrumel L on a screw-pin, q, at thc centre, from which the arm-s radiate.

W'hcre asqnare or oblongr radiator, likethat shown L iu thc drawings, is used, the wheel orlcver has'or may have four radial arnis p, so that whether the register be set horizontally or vertical] y, (as regards its length,) the twoarms will be in position t'or attachment ofthe cords.

When a round register is used, a lever wit-h only three arms is preierred.

lThe lever or wheel is hung to the plate 1l. by the screw-pin q inserted from -the back ofthe plate ,aud lpassing through the plate a, as seen at- B and C, and" 'by opening the valves, the screw maybe reached with a screw-driver, thus enabling the lever or wheel to be applied or removed, as may be desirable. y

W'hen the register is to be used at or ina iioor,'the wheel is removed, but when it. is to be used in a wall near the ceiling, the wheel is applied and operated as described.

Thus it will readily be seen that the register is l equally well adapted for use in either position, and

the-register heilig made for sale with the lever or wheel attached, it may be used in either positionv without other change than the simple removal of the wheelv if .the register is to be placed at the top of a wall.

I claim, in combination with a hot-air register, the wheel or lever o, when appliedto the outer side of tho' plate a, and in a plane parz'dlel therewith, to opera-te the valve-actuating slide, substantially as described.v
